Be it known that I, RUDOLF LINDNER, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented new and useful Improvements in Mechanical Movements, of whichthe following is a specification.

This invention relates to mechanical movements, and consists in certainimprovements in the construction thereof as will be here inafter fullydescribed and pointed out in the claims.

More particularly the invention relates to a mechanical movement inwhich a rotary motion is changed to a reciprocating motion.

The invention is illustrated in the accompanying drawings as follows:

Figure 1 shows a plan view of the rotating driving part. Fig. 2 a sideelevation of the device. Fig. 3 a plan view of the device. Fig. 4 acentral section through the reciprocating part and the driving scroll.

1 marks the rotating driving part. It is in the form of a disk. Abovethis is arranged a stationary frame made up of the side bars 2 and endpieces 3. The reciprocating member 4 has a projecting rib 5 whichextends down through the slots 6 formed between the side members 2. Alug 7 eX- tends from one end of the rib 5, and a rod 8 is secured tothis lug, and extends to any device to which it is desired to givereciprocating motion. Two pins 9 are slidingly mounted in thereciprocating part 4 extending through the rib 5. These have the heads10 which are somewhat larger than pins 9, and they are forced downwardlyby a spring 11. The spring 11 is in the form of a leaf or plate, and issecured to the reciprocating member by the screw 12. The sides have thelugs 13 at their ends and the pins of the carrying plates 14 are securedto the lugs 13 by screws 14 These have the inwardly extending flanges 15which come sufficiently close together to make the intervening slots 16sufficiently narrow to be of less width than the heads 10 of the pins,so that when the pins are lifted the heads will rest on the flanges 15and retain the pins in this upper position. In the operation of thedevice, the pins slide under the flanges 15 when moving in one directionand are lifted up onto them and slide on them when moving in theopposite direction.

The guiding part is provided with the scroll 19 preferably in the formof a groove MECHANICAL MOVEMENT.

17 formed between parallel ribs 17 A pin at one or the other side of thecenter is in the groove at all times, and as the rotating part is drivenin one direction the pins at each side of the center will move away fromthe center or toward the center in each instance, thus as each pin isdropped into the groove, and the other removed from it, thereciprocating part is reversed. This general scheme of convertingrotating movement into reciprocating movement is not new, but in all thedevices so far as I know the rotating part must be driven in onedirection. I place the cam 19 in continuation of the groove 17 at thecenter and the cam 18 in continuation of the same groove at the outerperiphery. These cams will raise the pins as they pass out of the endsof the groove to a position placing the head of the pin on the flanges15 and at an elevation that will carry the pin over the ribs 17 As thereciprocating part 4 is moved to either extremity the pin which iscarried on the flanges drops off that flange at the end of the movement,and the pin passes into the groove. On the other hand the continuedmovement of the rotating part carries the opposite pin upwardly by meansof either the cam 18 or 19 depending on the direction of the rotation.By operating the pins separately and independently one pin may be movedcompletely into its groove before the other pin disengages therefrom, asshown in Fig. 4. Pin 9 at the left will have been dropped into itsgroove before the head 10 of pin 9 at the right will pass from under theguide 15. At this point therefore, both pins 9 will be in grooves andwith a'little further movement pin 9 at the right will begin to rise andthe device reverses.

WVhat I claim as new is 1. In a mechanical movement, the co1nbination ofa driving part having a scroll thereon; a reciprocating part; engagingmeans independently mounted on the reciprocating part on each side ofthe center; and devices operating independently for alternately movingsaid means into and out of engagement as the driving part is rotated toactuate the reciprocating part.

2. In a mechanical movement the combination of a driving member having ascroll thereon; a reciprocating member; engaging means mounted on thereciprocating member at each side of the center, said means beingadapted to engage simultaneously the scroll .thereon; a reciprocatingpart;

at each side of the center; and devices independently operated foralternately moving said means into and out of engagement as the drivingmember is rotated to actuate the reciprocating member.

3. In a mechanical movement, the combination of a driving part having ascroll engaging means for locking the reciprocating part with thescroll; and devices for alternately throwing said means into and out ofengagement as the rotating part is rotated, said means acting with therotating part moving in either direction.

4. In a mechanical movement, the combination of a rotating driving parthaving a scroll thereon; a reciprocating part; engaging means forlocking the reciprocating part with the scroll at each side of thecenter of the rotating part alternately; and devices for actuating said.means to throw said means alternately out of engagement at each side ofthe center with the rotating part moving in either direction.

5. In a mechanical movement, the combination of a rotating driving parthaving a scroll thereon; and cams in continuation of each end of thescroll; a reciprocating part; and engaging means for locking thereciprocating part with the scroll, said engaging means being thrown outof locking position by the cams With the driving part rotating in eitherdirection.

6. In a mechanical movement, the combination of a rotating driving parthaving a scroll thereon; and cams in continuation of each end of thescroll; a reciprocating part; engaging means for locking thereciprocating part with the scroll, said engaging means being thrown outof locking position by the cams with the driving part rotating in eitherdirection; and a spring for throwing said engaging means into lockingposition.

7. In a. mechanical movement, the combination of a rotating part havinga scroll thereon; and cams in continuation of the scroll at each end; areciprocating part; sliding pins on the reciprocating part adapted to bethrown out of engagement with the scroll by said cams; and a guide forthe reciprocating part.

8. In a mechanical movement, the combination of a rotating driving parthaving a scroll thereon; and a cam in continuation of the scroll; aguide above the driving part; a reciprocating part operating on theguide; sliding pins on the reciprocating part adapted to be thrown outof engagement with the scroll by the cam; heads on said pins; and platesfor engaging the heads of the pins and locking the pins out ofengagement with the scroll; and springs for returning the pins.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
